The Escort: George Clooney
Before the luscious Italian model Elisabetta Canalis began accompanying The Man this awards season, there was this luscious American cocktail waitress. Although Larson did have some showbiz experience (if that's what you consider winning Fear Factor), she was at the Whiskey Bar in Vegas just months before becoming, in 2008, the first acknowledged Clooney girlfriend to accompany him to the Oscars.

The Morning After: Larson went from delivering drinks to modeling to being named to People's most-beautiful list and, after nearly a year, to being single again. Apparently doing a lot of yoga, too.

The Escort: Mel Gibson

Gibson was married to former dental nurse Robyn Moore until the whole "sugar tits" thing kicked in and they split in 2009. As soon as the ink dried on divorce papers, Mad Max began appearing with this mysterious Russian woman.

The Morning After: The two continue to be tightly linked both personally — they have a child together, to go with the seven from Gibson's first marriage — and professionally, since she's apparently one of those mysterious Russian pop stars and signed to his label Icon Records.
